Please Help! Need to find Manhwa!

I read it a while back and while I perfectly remember the story and characters I cannot for life the of me remember the name!
A guy with brown hair and a middle part is in love with his childhood best friend and has been secretly pining for him for years. Suddenly a black haired dude with straight hair begins hanging out with them through connections with the childhood friend I believe. The brown haired guy gets super jealous and competitive as he believes the new guy likes his best friend as well. Eventually the best friend goes on a trip of some sorts and leaves them to hang out with each other alone, they spend time together and it becomes a rivals to lovers story and the brown haired guy ends up falling in love with the new guy.
it was a super cute story and I really want to remember the name to reread!
